Cory first received treatment for his alcohol addiction when he was 19, although his recent stay in rehab was for substance abuse.

Yesterday, pathologists were focusing on the actor’s final weeks as his autopsy was carried out.

British Columbia’s chief coroner, Lisa Lapointe, said: “The exact nature of those examinations will depend on investigative findings within the next day or two as information is gathered from medical records and discussions with family take place.”

Police are set to interview his fiancée and co-star Lea Michele, 26, as well as further question his friends who he had been drinking with in the days before his death to ascertain key details of his lifestyle.
